We're all still a little unclear on why we're getting a spiritual successor to Eternal Darkness instead of a true sequel. We'll take what we can get, but could there be an issue with Nintendo preventing a true sequel in name? That doesn't seem to be the case, as the official SotE website has this to say.
We have been in constant communication with Nintendo, and they have been very supportive of our endeavour to bring this game to their platform.
Let's hope both parties are speaking amicably! Thanks to Autosaver for the heads up!
